Yes, I have had a bad experience.  Just a prior to FDA approval, I had silicone implants as part of a clinical research trial at Vanderbilt.  That was 11/05.  I became very sick immediately following the surgery.  I had turned 50 and was willing and able to pay the $6,500 required to participate in the study.  Following the surgery, I became extremely ill and spent the next 10 months in doctors' offices and in bed.  I thought my life was done.  I was totally disabled and unable to care for myself and family.  After 10 months it suddenly occured to me that the onset of my symptoms coincided with the implant surgery.  I had saline implants for 10 years prior so I never made the connection.  Nearly all of the health issues disappeared once the silicone implants were removed.  Now I know of at least a dozen other women who had the same reaction to silicone implants.  It is almost 2 years since the silicone implants were removed and I have worked very hard towards my recovery. There are many women who cannot tolerate the chemicals in silicone implants, many of which are toxic, but the doctors and implant manufacturers do not tell you that because they make more money on the silicone implants vs the saline ones.  It is not the silicone that makes you sick.  Just google silicone implants and chemicals. Eventually you will discover that there are literally dozens of carcinogens/neurotoxins in silicone implants that are potentially harmful to your health.  I could write a book about this experience, and perhaps one day, I will.  Today my focus is just getting well-
